改革后的新SAT考试
数学难度 难度阅读难度 阅读能力
数学部分难度提高，知识点考查由广度向深度转变，题目划分“可使用计算器”和“不可使用计算器”两个部分，增加了系列问题，即一个场景或者背景下出现多个问题，知识点考查涉及高等数学的简单内容，数学题目变得更长，应用题的情景更写实。 难度增加，需补充美国历史政治常识增加美国建国史的相关文章，增加体现美国基本价值观的文章和循证题和图表题两种全新的题型。 文法成绩取决于阅读能力，语法题，都将包含在文章内部的句子中，考查内容更加通俗，优化句子和句子改错题型则不再出现。
基本题型 形式
考试基本形式的改变，总分从2400回到1600分，选择题选项从五个变为四个，错选不再倒扣分。 用时50分钟，新SAT是先阅读一篇长篇阅读文章，然后对文章观点和论据之间的关系进行归纳整理。
SAT阅读备考技巧
单词扎实 句子理解
在托福备考的基础上,积累SAT阅读高频词。虽然有些单词不认识，但能通过上下文推断出来，这也是SAT阅读对考生的一项重要要求。 面对复杂长难句，要能做到识别主干，把握作者在句子中流露出的的基本情感态度，懂得在把握主要信息的前提下适当舍弃细枝末节。
学会阅读 阅读积累
要注意加强把握文章论证过程或行文思路的意识，关注文中逻辑关系词。主动阅读,边读边思考作者写了什么、为什么这么写、怎么写的问题。 大量阅读英文原著，提升英文的阅读理解能力。阅读是量的积累，一定要尽早着手，大量阅读，这才是实现阅读水平质的飞跃的根本增加。
sat语法之as的用法
As可以用做的词性：代词，介词，副词，连词
一、作代词（关系代词）
As作关系代词引导定语从句可以单独使用，也经常与一些词连用
1. 用在the same……as 结构中
Eg：
He bought the same refrigerator set as you had.（做宾语）
The same accident as happened to you, had happened to me.（做主语）
He is not the same playboy as we knew.
This is the same book as I lost.（这是我丢失的那本书）
对比：This is the same watch that/which I lost.(是同一只手表)；所以same和such后面有时也可以用who which that引导从句，只是意义上有时会有差别。
2.用在such as 结构中
I don’t like such books as he re**mends.
He is not such an idiot as he looks.
Such a dog as I keep is called bulldog.
Children love such people as love them.(主语)
Such a student as works hard will succeed.(主语)
注意such as后面有时跟一些名词作为例子，而不是从句。可以such as+例子，也可以such+名字+as+例子
He has such books as Iliad and Hamlet.
He has many books, such as Iliad and Hamlet.
Many books are available in Manhattan English, such as Iliad and Hamlet.
Some cities have millions of people , such as Beijing and New York.
3.so+ adj+a/an+N.+as结构（注意对比such a /an+adj）
He is not so weird a person as he was.
He can write so interesting a story as moves us to tears.
He did it in so peculiar a manner as surprised me.
4. as单独使用引导一个定语从句，先行词可以是一个名词、句子、短语
He shouted at the little boy, as is often the case.(非限制性定语从句，as代指前面整个句子)
As is well known(to everybody), the moon travels round the earth.
To shut eyes to facts, as many of you do, is really ridiculous.(不定式作为先行词)
二、 作介词
As作为介词使用比较简单，一般可以理解为“作为……”
He travels to China as a tourist.
As a legal member of the organization, our **pany attended the conference.
The bomb was disguised as a package.
He works as an accountant.
You can use that glass as a vase.
三、 作连词
1.“当……时候”“随着……”——when while，引导时间状语从句
The girl dances as she sings on stage.两个动作交替进行
He looked behind from time to time as he went forward.
As time went on, she became increasingly mature.
2.表示原因“由于”“既然”，引导原因状语从句—since 常常表示一个显而易见的原因或者大家都知道的原因。
As you were out, I left a message.
As you are not feeling well, you may stay at home.
She may need help as she’s new here.
3.=in the way in which表示方式，引导方式状语从句
They did as I had asked.
She lost it ,just as I said she would.
You should speak English as Americans do.
4.表示“虽然”“尽管”，引导让步状语从句（常倒装）= although;
Happy as they were, there is something missing.
Child as he is , he knows much.
**As+adj/adv+as结构：“与……一样”,否定形式是not so/as +adj/adv+as
This movie is as exciting as that one.个是副词，第二个是连词
The dictionary is not so/as usefull as you think.
**若有times，twice，quarter等类似词时，要放在as前面

常用的短语：
As soon as possible
As+adj/adv+ as usual/before
As long as(引导条件状语从句)
As far as 就……而言；直到… 远到…
